n Be it known 4that l, lFnRNaNno CASA- BLANoAs, a subject of the `King of Spain, re#

siding at San Olegario 15, Sabadell, Spain,-

have invented certain new and useful lmproyements in Spinning-Framesg and-l do l hereby declare the following to be a' full,

clear, and exact description of the' invention, such as will enable others skilled lin the art to which it appertains to make and use the same. ,Y

Y My present invention relates to improvements in spinning frames, and consists morel particularly in improvements in such spim ning frames as are shown, forinstance, in

my prior Patent No. 1,147,676,issued`luly 20, 1915. Spinning frames of this type` consist generally in'drawing rollers for operating upon ,the roving, which' theyv receive from a pair of endless belts actuated'frorn` ldriving rollers, and having, their forward ends running about guiding rods'or rollers which are located in close proximity to said drawing rollers and direct the bers tangentially therebetween. ln all suchwprior devices. the guiding elements, vv`vh-ichfu'sually consist of rollers lor stationary rods, are so relatively placed as to cause great-pressure 'l upon the belts at this point, which pressure is transmitted to the roving passing therebetween. This pressure is an unyielding pressure, and in this respect'di'erent from that exerted upon the roving by the belts.-

Moreover, this pressurev is apt to increase following upon the `accumulation. of lint or particles of fiber collectin on the guiding elements, which has ythe e5 their diameter land consequently forcing the belts more closely together, and exerting greater pressure on the roving as it passes from between the-belts and to .the drawing. y

thread which' is more regular and uniform. Broadly stated, .the invention consists in' the provision of belts of a material possessing ahigh degree of rigidity, and in dispos- :as occasion demands; likewise consistingl preferably of stationary rods or revolving rollers, may be employed,`

lDriving' rollers 5 and 6 are provided in rear of the guiding elements 1 and 2, and over.

these 'rollers and elementsfare trained the feeding belts 7 and 8,. These beltsv 7 and 8 are of 'a material 'possessing afhigh degree of from fthe, guiding 'elements 1 and 2, as clearlyshown in Figs. 1 and 2;,'ftherebyi'afs ing elements and permitting the belts `7 and 8 to' yield at thispoint in a 'manner similar to the yielding of the belts between the drivvrigidity,so,that said belts willstand 'out fording aclearance space between said guiding rollers 5 and 6 and said guiding"elef ments. These guiding elementsland 2 may be either stationary rods-or rollersltted to tuted by non-rotatable rods, thepassage of the belts 7 and 8 thereover wlll have a brushing and'- wiping edect, such as `will maintain the. same clear at all times and prevent accumulations oflint or other par- 8 are driven there' 'loo 30 -`shown, wherein one guiding element, 2, is

ticles tendingto increase their diameter and lessen the clearance space therebetween.

Referring now more particularly to Fig. 3, the guiding elements are here dispensed with, and pressure elements 9 and 10, which may be either rods, rollers, or'other devices found practical for this '-purpose, are prol vided, and lo'cated'in contact with the outer 9 and 10 in theposition shown in Fig.' 3,

force the belts 7 and 8 more closely into contact than the arrangement shown in Fig. 1,

and -thereby produce' a greater pressure on the roving 13, which pressure, however, is j constant .and uniform. -The pressure elejments 9 'and 10 are equipped with rings 26 for preventing any side shifting of the belts.

In this. form oftheinvention it will be noted thatthe forward ends of the belts 7 and 8 are unsupported, except bythe indirect' action ofthe guiding elements 9 and 10,

such construction andarrangement insuring of no abnormal pressure on the roving 13 the same is thrown forward by the rollers 3 and 4.

In Figi. 4 ,a 'modified arrangement is retained while.the companion guiding eler --mentis dispensedwith, and the forward end of the'belt 7 leftunsupported at this point.

' by the. pressure element 9, no corresponding pressure element being provided for the belt 8.v It is obvious that the guiding elev nient 1 might be retained andthe element 2 The belt 7 is, however, indirectly supported dispensed with, the belt 8 in such case being lthe pressure elevin Fig. 6 is Shown@ bracket having bearv `ings 1 and 2 for receiving the journals of f4.5

the guiding elements 1 and 2, such bracket being provided withvan arm 18 -fitting the sleeve 23 on thebearing of the upper draw-- ing roller 3. vThereis also a rearwardly disposed -arm 16 on the bracket 21 connected, as by bolt24, with the framework 15 of the machine. Q

In Fig..7. the-bracket is shown provided -with bearings`9.v and 10 for receiving the 'ends of the pressureelements 9 and 10, the other parts being similar to what is shown in Fig.,6,and what is already described.

F or the Amodification off the invention shown' in Fig 4, 'the ,bracket 'as illustrated iii Fig. 8 is.` required with'a bearing 9A for'the pressure element l9 and a bearing 27 for the guiding element 2.

The rolls and 'other parts heretofore de- 7 'scribed are supported fon bracket 27 in the mannershown in Fig. 1.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit ofmy invention, and therefore I do not. wish to be limited to such features except as may be required by the claims.

1. In a spinning frame, the lcombination ofa pair of endless belts for conducting the roving to the drawing rollers, said belts being slack so/as to take a certain convexity due to their own rigidness, a pair of driving Vrollers f or said belts which force the belts against one another producing a strong pressure upon the roving carried by said belts, and means to guide the front curve or loop of said belts arranged so as not to exert a direct vpressure upon the part of the belts which. holds the roving, in order that the pressure of the belts upon the roving may be soft and resilient.

2. In a spinning frame, the combination A of a pair of endless belts for conducting the fibers t the drawing rollers, said belts being slack soas to take the convexity `resulting from their own rigidness, a pair of driving v rollers that compress said belts and drive them, a pair of guiding rods arranged inside of the-front curve or loop of said belts, these rods being 'sufficiently separated one fro` the other so as not to exert a pressure upo rthe parts of the belts which hold the rovin. 3. n a spinning frame, the combi/nation of a pair of endless belts for conducting the roving'to the drawing rollers, said belts being slack so as to take the convexity resulting Afrom their own rigidness, a air of drivingrollers for said belts, a pair of guiding rods arranged inwardly of the front curve or loop of said belts, said rods being separated one from another so as not to exert any pressure upon the parts of the belts rods applied to the outward side of the belts in order to increase the resilient pressure exerted by said belts on the roving.

4. In a spinning frame, the combination of a pair of belts for conducting the'roving to the drawing rollers, said belts being slack sov as to take the convexity resulting from their own ri `dness, a paia` of driving rollers for said elts and a pair of outer rods applied to the outward sides of the belts in order to guide their front curves or loops and to increase the resiliency of said belts.
